It should be noted that the 29-year-old brother of Backstreet Boy Nick Carter did not use the words “gay” or “bisexual” in his tweet.

He concluded the passage with a quote he attributed to singer-songwriter Boy George, who is gay: “I’ve never felt as though I didn’t belong, I just acted as though I did.”

It’s been a challenging year for Carter, who is best known for his infectious 2000 single, “Aaron’s Party (Come Get It).” In July, the star was arrested in Georgia on suspicion of driving under the influence and drug possession.

Carter, who has been frank about his struggles with depression, substance abuse and eating disorders in the past, has since returned to the concert stage as part of a national tour. His next performance is slated for Aug. 10 in Brandon, Florida.
